View Full Version : 45GAP barrel change
I was wondering if the barrel of the 37 could be changed to allow it to shoot a regular 45 round? There might not be one out yet but it seems like a good idea.
A regular .45ACP round is too long for the magazine. That's why Glock created the .45GAP.
Ok, thanks. What do you think will happen with this round? Will it take off and be readily available?
When the .40S&W was introduced around 1990, ammo selection was limited and hard to get.
When the .357Sig was introduced around 1996, ammo selection was limited and hard to get.
Both are readily available today. I expect the .45GAP to follow a similar path.

I look at it this way: I can shoot a Glock 22 and put at .40" round out of the muzzle at about 400 ft/lbs, or I can shoot a Glock 37 and put a .45" round out the muzzle at about 400 ft/lbs. Bigger holes is better!;)

agreed :) plus like all new rounds ,it will take time ,and catch on ,it will catch a niche is some way or another, my ffl guy is police officer he said his department already looking into it and him and buds getting g37 ,so it s just matter of time, hj
speaking of time ,im still waiting grr few more days~2 ~2 ~2

problem with that thinking is the .40 smith n wesson and the .357 sig created their own nitch whareas the 45 gap is introduced in a market where their is already the 45 ACP.I feel this will always be a novelty round.lets face it on this site its well excepted but remember overall (wonderful world of firearms)glocks themselves are exactly a mainstram gun make.

The 357 sig came out in '94 I think. I had one of the first ones in a P229 and ammo was still 3 to 6 months away. It took a few years to catch on, I know. I couldn't give the gun away in it's first year. The 357 sig is just a 9mm that's much faster. It's still a 9mm though. The .40 is a 10mm that's shorter and less powerful and these took off. The .45 gap is faster than a .45 auto and fits small framed guns. You said there already was a .45 ACP, there already was a .40 aka 10mm and a 9mm. (40 S&W and 357 Sig) under a new name is all they are. .40 is more popular than the 10mm even though the 10mm is faster and harder hitting than the .40 and you know why? The .40 fits small framed guns. Recoil isn't a factor on 10mm vs .40 either because if that were true then the 357 Sig would have never made it. Most folks have small to medium hands and a small frame gun will always win over a big frame.
People do this every single time a new round comes out. It's nothing new. These same exact people always end up with one on down the road too. The 45 GAP will make it because Glock will push it hard just like Sig did. I'm sure a few garden salad commandos with nothing else to do will pick everything I said apart, but what I said is the truth IMHO.
Well, I'll bring this up again, since no one has answered my question yet:
Is it possible to ream a G37 barrel to fit 45 ACP, and use short OAL hollowpoint ammo? I ask because, when I looked at a loaded G37 magazine, there seemed to be alot of clearance between the nose of the round, and the front inside edge of the mag. JHPs in general are shorter than FMJ - would this difference be enough?

Just take it to a smith and try it and see. My .45 ACP rounds get stuck in the 45 gap mag even with the short corbon 165 gr.
Willard,
If a short .45acp would work, I don't think Glock would have wasted research, development and testing time necessary to bring the .45GAp into being.

DannyR,
I didn't mean to insinuate that Glock's R&D efforts were wasted. It's just that I realize that when Glock releases a design, they want it to be absolutely reliable with ALL ammo. That's why I wondered if the G37 could be made to feed certain 45ACP loads (reliably). Kinda like that pocket 32ACP (Seecamp?) that is designed around, and recommends using only Silvertip ammo.

Danny,
Isn't it likely that .45GAP conversion barrels will be made to work in G30's and G21's? I don't know what anybody's motivation would be to do that, but seems to me it would work.
Somebody posted that the .45GAP is "faster" than .45ACP. Is a 230gr. GAP faster than a 230gr. +p .45ACP?
Also, does anybody have an opinion as to whether the paucity of mag capacity will deter the .45GAP's acceptance for l.e. use?
I haven't inspected a .45GAP mag, but somebody on another thread said that there were restricting ribs in the sidewalls of the GAP mags, like the G21 Klintonista mags. If the ribs weren't there, wouldn't there perhaps be room for another round or two?

Walter, I know you asked this question to Danny but I'd like to comment on the mag issue if you don't mind. I think it's a case of you have to rob Peter to pay Paul. You lose 3 rds but gain a much smaller grip that will fit more hands. There also won't be any leo mags because the G37 is at full cap now.
Walter,
Winchester has not yet published any stats on their 230-gr GAP ammo, so nobody can make any reliable claims. I would expect at least 920 fps out of it.
A .45GAP conversion barrel can certainly be made for G21 and G30 pistols if any demand developes. Right now there are only 2,000 G37's in the USA.
The mag tube has no obstructions. You can only get 10 rounds of fat 45 in that tube. L.E. does have the option of adding a #7151 "+" base, which will increase the capacity at least 1 round, maybe 2.
When comparing .45's to .45's, I don't think 10+1 or 11+1 rounds to be a drawback. Comparing .45's to 9mm regarding capacity is a 90 year old controversy that will never be resolved.

Danny, et al, thanks for the info. Somebody posted, with an air of complete authority on another thread, that the .45 GAP mags did have ribs (he said "shallow ribs) in the sidewall.
Comparing mag capacity for 45GAP to either 9mm or .45ACP is irrelevant to l.e. use. The comparison would be 11 rounds or 45GAP v. 15-17 or so rounds of .40 Shicts und Weasel.
Having wasted a lot of $$$ and time over the past few years playing around with .400 Cor-Bon and .40 Super, I think I've learned my lessons about such conversions. I doubt that I'd have any interest in a conversion barrel for G21's or G30's, as there just isn't anything "exciting" to me about this abbreviated .45 round. Since I carry my G30 very comfortably and enjoy doing range work with my G21, I guess I'll sit this one out on the sidelines.
Best of luck to all of you who are "investing" in the G37; just doesn't move me at the moment.
Bob over on the "Bull Dawgs>Some more thought/questions on .45GAP" thread posted a great pic of his G37 Mag with 11 rounds in it. As you can see, the follower is sticking out of the bottom of the tube. (Turn on Tootsie-roll Professor Owl voice mask.) So, it is my humble opinion that, in it's present configuration, that max capacity for the G37 is 10 rounds of 45GAP ammo. (Turn off Tootsie-roll Professor Owl voice mask.)
;f
We gotta have fun too...
Maybe I shoulda said it this way, "One, two, ...ten. Ten rounds in a G37 magazine."
Or (more likely), "One, two, " ...bang, bang, bang... "We'll never know the total... " ..bang, bang, bang...
